Dozens injured in South Carolina train crash

Federal investigators are planning to give an update on their probe into a deadly crash between a freight train and a passenger train in South Carolina. The National Transportation Safety Board says on Twitter that the agency will hold a meeting briefing at 4 p.m. Monday near the Columbia Metropolitan Airport.

Board Chairman Robert Sumwalt and other investigators are on the ground in Cayce (CAY-see), where an Amtrak train slammed into a freight train early Sunday, killing a conductor and an engineer. More than a hundred people were injured.

Sumwalt told reporters Sunday that a switch was in the wrong position and that a GPS-based system called “positive train control” could have prevented the crash. The system knows the location of all trains and the positions of all switches to prevent the kind of human error that can put two trains on the same track. (AP)
